After the July 23rd Oakland "Day on the Green" show, a Bill Graham staffer was severely beaten for asking Peter Grant's [Zeppelin's manager] kid to return signage, torn down from dressing room doors. After an initial kick in the groin by Drummer, John Bonham, Zeppelin "security forces", including Grant, locked the BGP employee in a trailer and savagely beat him. Led Zeppelin's second Oakland show took place only after Bill Graham signed a letter of indemnification absolving Zeppelin from responsibility for the previous night's assault. The letter, signed by Graham under duress and with his left hand, was considered invalid, and Bonham, Grant and two security thugs were arrested.

Settling in Haight-Ashbury in the 60's, Wolman was surrounded by Janis and the Grateful Dead in close-by digs. Wolman was soon accompanying journalist Jann Wenner to the now famous and genre-defining Mills College conference on rock music. Wenner happened to be the founder of Rolling Stone magazine. He liked Wolman's style, offered him a job and Wolman launched as the first official document-er of the new psychedelic age. Beginning with the magazine's opening issue, Wolman's photographs were windows on the parade of the different, the delightful and the doomed, and his pictures became the gold standard by which rock photography would be measured.
